 Bering Sea - Wikipedia, the free encyclopedia
The Bering (or Imarpik) Sea is a body of water north of, and separated from, the north Pacific Ocean by the Alaska Peninsula and Aleutian Islands.
The Bering Sea is one of the world's richest fisheries, and landings from Alaskan waters represents half the U.S. catch of fish and shellfish.

 Kamchatka: Bering Island
Bering was working in the employ of the Russia Navy, and had just discovered the coast of Alaska when he and his Russian crew attempted to sail back to Kamchatka across what later became known as the Bering Sea.
Although Bering himself died on Dec 8, 1741 and nearly one half of his crew perished, in the end it was the abundant sea life of Bering Island that saved them.
The sailors christened the enormous animals "sea cows," partly to distinguish them from the fish-eating fur seals (which Russians call colloquially "sea bears," as the fur seals' grizzled brown coats and aggressivness make them resemble Kamchatka's grizzly bears), and partly in recognition of their cow-like character, as they grazed among the seaweed.

 SeaWeb - Ocean Briefing Book
Steller sea lion populations in the Bering Sea and western Gulf of Alaska have declined by approximately 80%.
A 1998 paper in the journal Science considered that the decline of sea lion populations was forcing orcas, which normally fed on the pinnipeds, to switch their attentions to sea otters, and that it was this increased predation that was largely responsible for the sea otters’ decline in the region.
Sea ducks in the Yukon-Kuskokwim Delta have displayed high blood lead concentrations, suggesting their decline in that region may be at least partly due to exposure to lead shot.

 The Bering Sea: Seasons and Cycles of Change
The Chukchi Sea is the northern part of the Bering Sea, lying north and south of the Bering Strait, the narrow passage of water between Alaska and Siberia.
The basics: The Bering Sea is a polar sea, lying north of the Aleutian Island chain, between the state of Alaska and the northeastern section of Siberia, and bounded to the southwest by the northern Kamchatka Peninsula.
Sea urchins feed on kelp, so the kelp forests in the Gulf of Alaska and the Bering Sea were overgrazed, which affected all of the organisms associated with the kelp, including seabirds like puffins and kittiwakes.

 Cyberwest - Bering Sea ecosystem responding to changes in Arctic climate
The northern Bering Sea is experiencing a shift from arctic to sub-arctic conditions, noted the researchers in an article published in the March 10 issue of Science.
The northern Bering Sea provides critical habitat for large populations of sea ducks, gray whales, bearded seals and walruses, all of which depend on small bottom-dwelling creatures for sustenance.
If the biological trends observed by the researchers in the northern Bering Sea persist and are not reversible, the accompanying shift in species and ecosystem structure could have important implications for the role of the sea as a "carbon sink," said the NSF.

 BIOQUAKE IN THE BERING SEA   (Site not responding. Last check: 2007-10-20)
During winter gales, when the mixed layer reaches its maximum depth of 200m, the shallower regions of the Bering Seas are enriched by nitrogen, phosphorus and silica dredged from deeper regions by strong currents.
The shallow depth of much of the Bering Sea makes its ecosystem unusually sensitive to climatic fluctuations, and in 1997, a combination of events sent its climate and biology "crazy", according to Dr Robert Francis, a fisheries oceanographer of the University of Washington, Seattle.
Researchers in the Bering Sea watched the shearwaters increase the amount of fish in their diet to a level not previously recorded, to compensate for the lack of krill.

 Fog, Men, and Cutters: A History of the Bering Sea Patrol
The story of the USRCS and the USCG in the Bering Sea and Arctic is a study in microcosm of the multifaceted duties of the two services.
During the Bering Sea Controversy of the 1890s, when the United States and Great Britain teetered on the brink of war over the illegal killing of the seals, the work of the service multiplied and more cutters were needed.
Some of the enlisted men of the Bering Sea Patrol who died while serving in Alaska were buried where they met their fate, or were buried at sea and, thus, nothing remains to mark their final resting spot.

During the height of the last Ice Age, the Bering Sea was a vast grassland that served as the gateway for people migrating from Asia to North America.
The impacts of commercial fishing are compounded by natural fluctuations in the Bering Sea environment, which can be quite dramatic, and increasingly by the effects of global climate change caused by anthropogenic releases of greenhouse gases.
These include earlier breakup of summer sea ice, persistent warm waters, large blooms of marine algae called coccolithophorids, a large increase in the abundance of jellyfish (lasting from the early 1980s through 2000), and shifts in the abundance and distribution of fish and marine mammals.

 Bering Sea Arbitration - Wikipedia, the free encyclopedia
Bering Sea Arbitration, The important fishery dispute between Great Britain and the United States, which was closed by this arbitration, arose in the following circumstances.
The boundary between the two powers, as laid down by the treaty for purchase, was a line drawn from the middle of Bering Strait south-west to a point midway between the Aleutian and Komandorski Islands dividing Bering Sea into two parts, of which the larger was on the American side of this line.
By certain acts of congress, passed between 1868 and 1873, the killing of seals was prohibited upon the islands of the Pribiloff group and in "the waters adjacent thereto" except upon certain specified conditions.

 WWF | Bering Sea | About the Region
The Bering Sea plays an important part in the life cycle of some of the world's largest salmon populations, which spend their adult life in the Bering Sea before migrating up the rivers of Alaska and Russia's Kamchatka Peninsula to spawn.
Among the sea's wildlife species are the endangered bowhead and northern right whales, the highly endangered Steller sea lion, the northern fur seal -- which is now considered "depleted" according to the U.S. Marine Mammal Protection Act -- and the polar bear, which is listed in Russia's Red Data Book of Rare and Endangered Species.
Illustrating the tremendous ecological value of this region are the Bering Sea's Pribilof Islands, a group of four islands which are often called the "Galapagos of the North." Located at the edge of the continental shelf, the Pribilofs benefit from nutrient-rich currents called upwellings that add to the richness of the waters around the islands.
